communications system includes terminal devices 1A to 1C and a base
station device 3. Hereinafter, the terminal devices 1A to 1C are
also referred to as a terminal device 1.
[0019] The base station device 3 may include one or both of an MCG
(Master Cell Group) and an SCG (Secondary Cell Group). The MCG is a
group of serving cells including at least a PCell (Primary Cell).
The SCG is a group of serving cells including at least a PSCell

is used. An OFDM symbol is a unit of the OFDM time domain. An OFDM
symbol includes at least one or more subcarriers. An OFDM symbol
may also be converted to a time-continuous signal in generating a
baseband signal.
[0022] Subcarrier spacing (SCS) may be obtained by a subcarrier
spacing according to .DELTA.f=2.sup..mu.15 kHz, where .DELTA.f is
the SCS. For example, the subcarrier spacing configuration .mu. may
be set to any one of 0, 1, 2, 3, 4, and/or 5. The subcarrier
spacing configuration .mu. may also be provided by a higher layer
parameter for a certain BWP (BandWidth Part).
[0023] In the radio communications system according to the present
disclosure, a time unit T.sub.C is used to represent the length in
the time domain. The time unit T.sub.C may be obtained by
T.sub.C=1/(.DELTA.f.sub.maxN.sub.f). .DELTA.f.sub.max may be the
maximum value of the subcarrier spacing supported in the radio
communications system according to the present disclosure.
.DELTA.f.sub.max may be .DELTA.f.sub.max=480 kHz. N.sub.f may be

regardless of .mu.. The length of the subframe may be obtained
regardless of the subcarrier spacing .DELTA.f. In other words, the
subframe configuration may be obtained regardless of .mu..
[0026] The number and index of slots included in a subframe may be
obtained for the configuration .mu. of a certain subcarrier
spacing. For example, the first slot number n.sup..mu. may be
obtained in ascending order in the range of 0 to N.sup.subframe,
.mu..sub.slot-1. The number and index of the slots included in the
frame may be obtained for the subcarrier spacing configuration
.mu.. For example, the second slot number n.sup..mu..sub.s, f may
be obtained in ascending order in the range of 0 to N.sup.frame,
.mu..sub.slot-1 in the frame. Consecutive N.sup.slot.sub.symb OFDM
symbols may be included in one slot. N.sup.slot.sub.symb may be
obtained based on at least a part or all of the slot configuration
and/or the CP (Cyclic Prefix) configuration. The slot configuration

subcarrier spacing configuration .mu. is 2, and the CP
configuration is a normal CP, N.sup.slot.sub.symb=14, N.sup.frame,
.mu..sub.slot=40, N.sup.subframe, .mu..sub.slot=4. Furthermore, in
FIG. 2B, when the slot configuration is 0, the subcarrier spacing
configuration .mu. is 2, and the CP configuration is an extended
CP, N.sup.slot.sub.symb=12, N.sup.frame, .mu..sub.slot=40,
N.sup.subframe, .mu..sub.slot=4. The N.sup.slot.sub.symb when the
slot configuration is 0 may correspond to double the
N.sup.slot.sub.symb when the slot configuration is 1.
[0028] Hereinafter, the physical resources will be described.
[0029] An antenna port may be defined by a channel on which a
symbol transmitted at one antenna port can be estimated according
to the channel on which other symbols are transmitted at the same
antenna port. If a large-scale property of a channel on which a
symbol is transmitted at one antenna port can be estimated
according to the channel on which a symbol is transmitted at
another antenna port, the two antenna ports are referred to as QCL
(Quasi Co-Located). The large-scale property may include at least

corresponding to the first antenna port and the receiving beam
assumed by the receiving side corresponding to the second antenna
port are the same. For beam parameters, the first antenna port and
the second antenna port being QCL may also indicate that the
transmission beam assumed by the receiving side corresponding to
the first antenna port and the transmission beam assumed by the

same. The terminal device 1 may assume that the two antenna ports
are QCL if the large-scale property of the channel on which the
symbol is transmitted at one antenna port can be estimated
according to the channel on which the symbol is transmitted at
another antenna port. The two antenna ports being QCL may also
indicate that the two antenna ports are assumed to be QCL.

referred to as a downlink carrier (or a downlink component
carrier). In the uplink, a carrier included in a serving cell is
referred to as an uplink carrier (uplink component carrier). The
downlink component carrier and the uplink component carrier are

radio parameter set, the resource element is determined by a
frequency domain index k.sub.sc and a time domain index l.sub.sym.
The resource element determined by the frequency domain index
k.sub.sc and the time domain index l.sub.sym is referred to as a
resource element (k.sub.sc, l.sub.sym). The frequency domain index

transmission and reception using only a subset of the resource
grid. A subset of the resource grid may also be referred to as BWP,
which may be obtained based on at least a part or all of higher
layer parameters and/or the DCI. BWP is also called a bandwidth

instructed to perform transmission and reception using all sets of
the resource grid. In other words, the terminal device 1 may be
instructed to perform transmission and reception using a part of
frequency resources in the resource grid. One BWP may be composed
of a plurality of resource blocks in the frequency domain. One BWP
may be composed of a plurality of consecutive resource blocks in
the frequency domain. A BWP configured for a downlink carrier is
also referred to as a downlink BWP. A BWP configured for an uplink
carrier is also referred to as an uplink BWP.
[0035] One or more downlink BWPs may be configured for the terminal
device 1. The terminal device 1 may attempt to receive a physical
channel (for example, PDCCH, PDSCH, Synchronization Signal (SS)/
PBCH (Physical Broadcast Channel), etc.) in one downlink BWP of one
or more downlink BWPs. The one downlink BWP is also referred to as
an activated downlink BWP.
[0036] One or more uplink BWPs may be configured for the terminal
device 1. The terminal device 1 may attempt to transmit a physical

[0037] A set of downlink BWPs may be configured for each of the
serving cells. The set of downlink BWPs may include one or more
downlink BWPs. A set of uplink BWPs may be set for each of the
serving cells. The set of uplink BWPs may include one or more

[0051] Hereinafter, physical channels and physical signals
according to various implementations of the present disclosure will
be described.
[0052] An uplink physical channel may correspond to a set of
resource elements that carry information generated in a higher
layer. An uplink physical channel is a physical channel used in an
uplink carrier. In the radio communications system according to one
aspect of the present disclosure, at least some or all of the
following uplink physical channels are used. [0053] a Physical
uplink control channel (PUCCH) [0054] a Physical uplink shared
channel (PUSCH) [0055] a Physical random access channel (PRACH)
[0056] The PUCCH may be used for transmitting uplink control
information (UCI). The uplink control information includes channel
state information (CSI), a scheduling request (SR), and part or all
of a HARQ-ACK (Hybrid Automatic Repeat request ACKnowledgement)
corresponding to transport blocks (TBs) (MAC (Medium Access
Control) PDU (Protocol Data Unit), a DL-SCH (Downlink-Shared
Channel), and a PDSCH (Physical Downlink Shared Channel)).
[0057] The HARQ-ACK may include at least a HARQ-ACK bit
corresponding to at least one transport block. The HARQ-ACK bit may
indicate ACK (acknowledgement) or NACK (negative-acknowledgement)
corresponding to one or more transport blocks. A HARQ-ACK may
include at least a HARQ-ACK codebook including one or more HARQ-ACK
bits. The HARQ-ACK bit corresponding to one or more transport
blocks may indicate that the HARQ-ACK bit corresponds to a PDSCH
including the one or more transport blocks.
[0058] The HARQ-ACK bit may indicate ACK or NACK corresponding to
one CBG (Code Block Group) included in the transport block.
HARQ-ACK is also referred to as HARQ feedback, HARQ information, or
HARQ control information.
[0059] A Scheduling Request (SR) may be used to request PUSCH
resources for initial transmission. The scheduling request bit may
be used to indicate either a positive SR or a negative SR. The
scheduling request bit indicating a positive SR may also be
referred to as "transmitting a positive SR." A positive SR may
indicate that the terminal device 1 requests a PUSCH resource for
initial transmission. A positive SR may indicate that the
scheduling request is triggered by higher layers. A positive SR may
be transmitted when the higher layer indicates transmission of a
scheduling request. The scheduling request bit indicating a
negative SR may also referred to as "transmitting a negative SR." A
negative SR may indicate that the terminal device 1 does not
request PUSCH resources for initial transmission. A negative SR may
indicate that the scheduling request is not triggered by higher
layers. A negative SR may be transmitted when the higher layer does
not indicate transmission of a scheduling request.
[0060] The channel state information may include at least a part or
all of a channel quality indicator (CQI), a precoder matrix

and the PMI is an index indicating a precoder. The RI is an index
indicating the transmission rank (or the number of transmission
layers).
[0061] The PUCCH supports PUCCH format (PUCCH format 0 to PUCCH
format 4). The PUCCH format may be mapped to the PUCCH and
transmitted. The PUCCH format may be transmitted with the PUCCH.
The transmission of the PUCCH format may also indicate the

[0063] The PRACH is used for transmitting a random access preamble
(random access message 1). The PRACH is used in a part or all of an
initial connection establishment procedure, a handover procedure, a
connection re-establishment procedure, synchronization (timing
adjustment) for PUSCH transmission, and a resource request for the
PUSCH. The random access preamble may be used for notifying the
base station device 3 of an index (random access preamble index)
obtained from a higher layer of the terminal device 1.
[0064] In FIG. 1, the following uplink physical signals are used in
the uplink radio communications. The uplink physical signal may not
be used for transmitting information output from a higher layer,
but is used by the physical layer. [0065] An UL DMRS (UpLink
Demodulation Reference Signal) [0066] An SRS (Sounding Reference
Signal) [0067] An UL PTRS (UpLink Phase Tracking Reference
Signal)
[0068] The UL DMRS is related to transmission of a PUSCH and/or a
PUCCH. The UL DMRS is multiplexed with the PUSCH or PUCCH. The base
station device 3 may use the UL DMRS to perform the PUSCH or PUCCH

PUSCH is also referred to as an UL DMRS for PUSCH. The UL DMRS
related to the PUCCH is also referred to as an UL DMRS for
PUCCH.
[0069] The SRS may not be related to the PUSCH or PUCCH

PDCCH may include monitoring and detecting the PDCCH and/or the DCI
format transmitted over the PDCCH.
[0082] The control resource set may indicate a time-frequency
domain to which one or more PDCCH can be mapped. The control
resource set may be an area where the terminal device 1 monitors
the PDCCH. The control resource set may be composed of a localized
resource. The control resource set may also be composed of a
distributed resource.
[0083] In the frequency domain, the unit of mapping of the control
resource set may be a resource block. For example, in the frequency
domain, the unit of mapping of the control resource set may be six
resource blocks. In the time domain, the unit of mapping of the
control resource set may be an OFDM symbol. For example, in the
time domain, the unit of mapping of the control resource set may be

resource block group (RBG). The resource block group may be
obtained with six consecutive resource blocks.
[0085] The number of OFDM symbols that compose the control resource

[0087] The control resource set configured by the MIB is also
referred to as CORESET#0. CORESET#0 may be a control resource set
with index #0.
[0088] A certain control resource set may be a dedicated control
resource set. The dedicated control resource set may be a control
resource set configured to be used exclusively for the terminal
device 1. The dedicated control resource set may be obtained based
on at least a part or all of the dedicated RRC signaling and the
value of the cell radio network temporary identifier (C-RNTI).
[0089] The PDCCH candidate set monitored by the terminal device 1
may be defined in terms of a search area. In other words, the PDCCH
candidate set monitored by the terminal device 1 may be obtained
according to the search area.
[0090] The search area may be composed of one or more PDCCH
candidates with or more aggregation levels included. The
aggregation level of the PDCCH candidates may indicate the number

included in one control resource set. For each of the search area
sets, an index of a control resource set associated with the search
area set may be obtained.
[0094] The physical resource of the search area is configured by a
control channel element (CCE). The CCE is composed of a
predetermined number of resource element groups (REG). For example,
a CCE may be composed of six REGs. The REG may be composed of one
OFDM symbol of one PRB (Physical Resource Block). In other words,
the REG may be composed of 12 resource elements (RE). The PRB is
referred to as an RB (Resource Block) for simplicity.

Repeat request) control is performed for each transport block. The
transport block is a unit of data that the MAC layer delivers to
the physical layer. In the physical layer, the transport blocks are
mapped to the codewords, and modulation processing is performed for
each codeword.
[0109] The base station device 3 and the terminal device 1 exchange
(transmit and receive) higher layer signals in the higher layer.
For example, the base station device 3 and the terminal device 1

Resource Control message, RRC information: Radio Resource Control
information) in a radio resource control (RRC) layer. Furthermore,
the base station device 3 and the terminal device 1 may transmit

dedicated to the certain terminal device 1 is also referred to as
dedicated RRC signaling. The higher layer parameters specific to
the serving cell may be transmitted by using the common signaling
or by using the dedicated signaling. The UE specific higher layer
parameters may be transmitted to a certain terminal device 1 using
the dedicated signaling.
[0111] The BCCH (Broadcast Control Channel), the CCCH (Common
Control Channel), and the DCCH (Dedicated Control Channel) are

[0114] An example of a configuration of the terminal device 1
according to one aspect of the present disclosure will be
described.
[0115] FIG. 4 is a schematic block diagram of a configuration of a
terminal device 1 according to the present disclosure. As
illustrated, the terminal device 1 includes a radio
transmission/receiving unit 10 and a higher layer processing unit
14. The radio transmission/receiving unit 10 includes at least a
part or all of an antenna unit 11, an RF (Radio Frequency) unit 12,
and a baseband unit 13. The higher layer processing unit 14 is
configured to include at least a part or all of a medium access
control layer processing unit 15 and a radio resource control layer
processing unit 16. The radio transmission/receiving unit 10 is
also referred to as a transmission unit, a receiving unit, or a
physical layer processing unit.
[0116] The higher layer processing unit 14 outputs the uplink data
(transport block) generated by a user operation or the like to the
radio transmission/receiving unit 10. The higher layer processing
unit 14 performs processing of a MAC layer, a packet data
convergence protocol (PDCP) layer, a radio link control (RLC)
layer, and an RRC layer.
[0117] The medium access control layer processing unit 15 included
in the higher layer processing unit 14 performs processing of the
MAC layer.
[0118] The radio resource control layer processing unit 16 included
in the higher layer processing unit 14 performs processing of the
RRC layer. The radio resource control layer processing unit 16
manages various configuration information/parameters of the
terminal device. The radio resource control layer processing unit
16 configures various configuration information/parameters based on
the higher layer signal received from the base station device 3. In
other words, the radio resource control layer processing unit 16
configures various configuration information/parameters based on
the information indicating various configuration

Furthermore, the configuration information may include information
related to processing or configuring of a physical channel, a
physical signal (i.e., a physical layer), a MAC layer, a PDCP
layer, an RLC layer, and an RRC layer. The parameters may also be
higher layer parameters.
[0119] The radio transmission/receiving unit 10 performs physical
layer processing, such as modulation, demodulation, encoding, and
decoding. The radio transmission/receiving unit 10 separates,
demodulates, and decodes the received physical signal, and outputs
the information to the higher layer processing unit 14. The radio
transmission/receiving unit 10 generates a physical signal by
modulating data, encoding, and generating a baseband signal
(conversion to a time continuous signal), and transmits the
physical signal to the base station device 3.
[0120] The RF unit 12 converts a signal received via the antenna
unit 11 into a baseband signal (down-conversion) by quadrature
demodulation, and removes undesirable frequency components. The RF
unit 12 outputs the processed analog signal to the baseband
unit.
[0121] The baseband unit 13 converts the analog signal input from
the RF unit 12 into a digital signal. The baseband unit 13 removes
a portion that corresponds to a CP (Cyclic Prefix) from the
converted digital signal, performs fast Fourier transform (FFT) on
the signal from which the CP has been removed, and extracts the
signal in the frequency domain.
[0122] The baseband unit 13 performs an inverse fast Fourier
transform (IFFT) on the data, generates an OFDM symbol, appends a
CP to the generated OFDM symbol, generates a baseband digital
signal, and converts the baseband digital signal into an analog
signal. The baseband unit 13 outputs the converted analog signal to
the RF unit 12.
[0123] The RF unit 12 removes undesirable frequency components from
the analog signal input from the baseband unit 13 using a low pass
filter, up-converts the analog signal to a carrier frequency, and
transmits the analog signal via the antenna unit 11. Furthermore,
the RF unit 12 amplifies the power of the transmitted analog
signal. Furthermore, the RF unit 12 may control the transmission
power. The RF unit 12 is also referred to as a transmission power
control unit.
[0124] Hereinafter, an example of the configuration of the base
station device 3 according to one aspect of the present disclosure

[0125] FIG. 5 is a schematic block diagram of a configuration of a
base station device 3 according to the present disclosure. As
illustrated, the base station device 3 is composed of a radio
transmission/receiving unit 30 and a higher layer processing unit
34. The radio transmission/receiving unit 30 includes an antenna
unit 31, an RF unit 32, and a baseband unit 33. The higher layer
processing unit 34 includes a medium access control layer
processing unit 35 and a radio resource control layer processing

to as a transmission unit, a receiving unit, or a physical layer
processing unit.
[0126] The higher layer processing unit 34 performs processing of
the MAC layer, PDCP layer, RLC layer, and RRC layer.
[0127] The medium access control layer processing unit 35 included
in the higher layer processing unit 34 performs processing of the
MAC layer.
[0128] The radio resource control layer processing unit 36 included
in the higher layer processing unit 34 performs processing of the
RRC layer. The radio resource control layer processing unit 36
generates downlink data (transport block), system information, an
RRC message, a MAC CE, and other signals configured in the PDSCH,
or acquires the data from the higher node, and outputs the data to
the radio transmission/receiving unit 30. Furthermore, the radio
resource control layer processing unit 36 manages various
configuration information/parameters of each terminal device 1. The
radio resource control layer processing unit 36 may configure
various configuration information/parameters for each of the
terminal devices 1 via a higher layer signal. In other words, the
radio resource control layer processing unit 36 transmits/reports
information indicating various configuration
information/parameters. The configuration information may include
information related to processing or configuring of a physical
channel, a physical signal (i.e., a physical layer), a MAC layer, a
PDCP layer, an RLC layer, and an RRC layer. The parameters may be
higher layer parameters.
[0129] The functions of the radio transmission/receiving unit 30
are the same as the functions of the radio transmission/receiving
unit 10, and will not be repeated.
[0130] Each of the units (e.g., denoted with reference numerals 10
to 16) included in the terminal device 1 may be composed of a
circuit. Each of the units included in the base station device 3
may be composed of a circuit.
[0131] The terminal device 1 may multiplex the uplink control
information (UCI) on the PUCCH and transmit it. The terminal device
1 may multiplex the UCI on the PUSCH and transmit it. The UCI may
include the HARQ-ACK and/or the CSI.
[0132] A plurality of PUSCH types may be defined based on the type
of data (UCI, UL-SCH) that have been multiplexed on the PUSCH
before multiplexing the UCI related to the PUCCH on the PUSCH. For
example, the PUSCH of aperiodic CSI (aperiodic CSI on PUSCH), the
PUSCH of semi-persistent CSI (semi-persistent CSI on PUSCH), the
PUSCH of dynamic scheduling (dynamically scheduled PUSCH), and the
PUSCH of semi-static scheduling (semi-statically scheduled PUSCH)
may be defined. The aperiodic CSI is also referred to as an
aperiodic CSI. The semi-persistent CSI is also referred to as a
semi-persistent CSI. In the present implementation, the PUSCH for
dynamic scheduling does not include the random access message
3.
[0133] The PUSCH of the aperiodic CSI is a PUSCH on which the
aperiodic CSI is multiplexed. The aperiodic CSI is a channel state
information report that is performed aperiodically. The aperiodic
channel state information report may be indicated based on at least
the DCI format. The aperiodic channel state information report may
be indicated based on at least a predetermined value configured to
a code point of a CSI request field included in the DCI format.
[0134] The PUSCH of the semi-persistent CSI is referred to as a
PUSCH on which the UCI of the semi-persistent CSI is multiplexed.
The semi-persistent CSI is a channel state information report that
is performed semi-persistently. For the activation or deactivation
of the semi-persistent CSI report using the PUSCH, the terminal
device 1 determines whether a part or all of the following
requirements are satisfied. In other words, the semi-persistent CSI
report using the PUSCH is activated using at least the DCI
format.
[0135] Requirement A1: the DCI format is scrambled by a semi
persistent-channel state information-radio network temporary
identifier (SP-CSI-RNTI) obtained by the higher layer parameter
sp-csi-RNTI
[0136] Requirement A2: the specific DCI format field for activation
of semi-persistent CSI is set to a predetermined value indicating
the activation of semi-persistent CSI
[0137] Requirement A3: the specific DCI format field for
deactivation of semi-persistent CSI is set to a predetermined value
indicating the deactivation of semi-persistent CSI
[0138] The transmission of semi-persistent CSI may be activated
when Requirements A1 and A2 are both satisfied. The transmission of
semi-persistent CSI may be deactivated when Requirements A1 and A3
are both satisfied.
[0139] The PUSCH of the dynamic scheduling is dynamically scheduled
by the uplink grant of the DCI format. The PUSCH may include a
transport block. The PUSCH of the dynamic scheduling may be the
PUSCH scheduled based on the DCI format and not indicated by the
aperiodic CSI based on the DCI format.
[0140] The semi-statically scheduled PUSCH, which is scheduled by a
grant trigger, is a PUSCH on which PUSCH resources are
semi-statically allocated and a transport block is transmitted
according to the higher layer parameters. The semi-statically
scheduled PUSCH may include a type 1 semi-statically scheduled
PUSCH and a type 2 semi-statically scheduled PUSCH. For the type 1
semi-statically scheduled PUSCH, transmission in the time domain
may be indicated by a higher layer parameter timeDomainAllocation.
The type 2 semi-statically scheduled PUSCH may be triggered by an
uplink grant in the DCI format. A transmission interval
(periodicity) for the semi-statically scheduled PUSCH may be
obtained based on a higher layer parameter.
[0141] When the PUCCH does not conflict (overlap) with the PUSCH in
the time domain, the terminal device 1 may multiplex and transmit
the UCI related to the PUCCH on the PUCCH. When the PUCCH conflicts
(overlaps) with the PUSCH in the time domain, the terminal device 1
may multiplex and transmit the UCI related to the PUCCH to the
PUSCH, and may not transmit the PUCCH. The PUCCH may be a PUCCH
configured with the transmission of the UCI. The transmission of
the UCI may be provided based on at least the DCI format and/or the
higher layer parameters.
[0142] The UCI related to the PUCCH does not include an aperiodic
CSI. The UCI associated with the PUCCH does not include the
semi-persistent CSI that is activated by the DCI format.
[0143] When the PUSCH of the aperiodic CSI and the dynamically
scheduled PUSCH conflicts with the PUCCH in the time domain, the
terminal device 1 may multiplex the UCI related to the PUCCH on the
PUSCH of the aperiodic CSI and transmit the multiplexed UCI.
[0144] When the PUSCH of the aperiodic CSI and the semi-statically
scheduled PUSCH conflicts with the PUCCH in the time domain, the
terminal device 1 may multiplex the UCI related to the PUCCH on the
PUSCH of the aperiodic CSI and transmit the multiplexed UCI.
[0145] When the dynamically scheduled PUSCH and the semi-statically
scheduled PUSCH conflicts with the PUCCH in the time domain, the
terminal device 1 may multiplex the UCI related to the PUCCH on the
dynamically scheduled PUSCH and transmit the multiplexed UCI.
[0146] When a plurality of PUSCH (a set of PUSCH) conflicts with
the PUCCH in the time domain, the PUSCH for multiplexing the UCI
may be obtained based on at least an index of a serving cell to
which each of the plurality of PUSCH is mapped and/or the starting
position of each of the plurality of PUSCH. For example, when a
plurality of PUSCH of the same PUSCH type conflict with the PUCCH
in the time domain and the plurality of PUSCH are used for a
plurality of serving cells, the terminal device 1 multiplexes the
UCI related to the PUCCH to a serving cell with a lower identifier
value and transmits the multiplexed UCI on the PUSCH of the serving
cell. When a plurality of PUSCHs are transmitted in the serving
cell, the terminal device 1 may multiplex the UCI related to the
PUCCH to the first PUSCH in the time domain of the plurality of
PUSCH in the serving cell and transmit the multiplexed UCI.
[0147] FIG. 6 is a diagram illustrating selecting a PUSCH for
transmitting a UCI when a PUCCH including the UCI conflicts with
one or more PUSCHs in the time domain according to the present
disclosure.
[0148] In a first example, when the PUCCH 601 including the UCI
conflicts with the PUSCH 600 in the time domain, the terminal
device 1 transmits the UCI multiplexed on the PUSCH 600. The PUSCH
600 may be any one of a PUSCH of aperiodic CSI, a PUSCH of
semi-persistent CSI (semi-persistent CSI on PUSCH), a dynamically
scheduled PUSCH, and a semi-statically scheduled PUSCH. The PUCCH
including the UCI may be a PUCCH on which transmission of the UCI
is configured based on at least the higher layer parameters. The
PUCCH including the UCI may be a PUCCH on which transmission of the
UCI is instructed based on at least the DCI.
[0149] In the second example, when the PUCCH 612 including the UCI
conflicts with the aperiodic CSI on PUSCH 611 and the PUSCH 610 in
the time domain, the terminal device 1 multiplexes the UCI on the
PUSCH 611 carrying aperiodic CSI and transmits the multiplexed UCI.
The PUSCH 610 may be either a dynamically scheduled PUSCH or a
semi-statically scheduled PUSCH.
[0150] In the third example, when the PUCCH 625 including the UCI
includes a first PUSCH group (First PUSCHs), which includes one or
more dynamically scheduled PUSCH 622, 623, and 624, conflicts with
a second PUSCH group (Second PUSCHs) including one or more
semi-statically scheduled PUSCH 620 and 621, the terminal device 1
multiplexes and transmits the UCI to one of the PUSCHs of the first
PUSCH group.
[0151] In the fourth example, when the PUCCH 634 including the UCI
conflicts with a plurality of dynamically scheduled PUSCH 630, 631,
632, and 633 in the time domain, the terminal device 1 multiplexes
the UCI to the PUSCH 630 at the start in the time domain and to
which the serving cell has a low value of the serving cell
identifier and transmits the multiplexed UCI.
[0152] When the PUCCH including the UCI conflicts with one or more
PUSCH in the time domain, the PUSCH transmitted by multiplexing the
UCI is selected from the one or more PUSCH based at least on
whether each of the one or more PUSCH is a PUSCH of semi-persistent
CSI.
[0153] When the PUSCH of semi-persistent CSI and the PUSCH of
aperiodic CSI and/or the dynamically scheduled PUSCH and/or the
semi-statically scheduled PUSCH conflicts with the PUCCH including
UCI in the time domain, the terminal device 1 multiplexes and
transmits the UCI on the PUSCH of the semi-persistent CSI. When the
PUSCH of the semi-persistent CSI and the first PUSCH group
conflicts with the PUCCH including the UCI in the time domain, the
UCI is multiplexed and transmitted on the PUSCH of the
semi-persistent CSI. The first PUSCH group includes at least a part
or all of one or more PUSCH of the aperiodic CSI, one or more
dynamically scheduled PUSCH, and/or one or more semi-statically
scheduled PUSCH. For example, when the PUSCH of the semi-permanent
CSI and the PUSCH of the aperiodic CSI conflicts with the PUCCH
including the UCI in the time domain, the UCI may be multiplexed
and transmitted on the PUSCH of the semi-permanent CSI.
Furthermore, when the PUSCH of the semi-persistent CSI and the
dynamically scheduled PUSCH conflicts with the PUCCH including the
UCI in the time domain, the UCI is multiplexed and transmitted on
the PUSCH of the semi-persistent CSI.
[0154] When the PUCCH including the UCI conflicts with the PUSCH of
the semi-permanent CSI and the PUSCH of the aperiodic CSI in the
time domain, the terminal device 1 multiplexes and transmits the
UCI on the PUSCH of the aperiodic CSI. When the PUCCH including the
UCI conflicts with the PUSCH of the semi-persistent CSI and the
dynamically scheduled PUSCH and/or the semi-statically scheduled
PUSCH in the time domain, the terminal device 1 multiplexes and
transmits the UCI on the PUSCH of the semi-persistent CSI. When the
PUSCH of the semi-permanent CSI and the PUSCH of the aperiodic CSI
conflicts with the PUCCH including the UCI in the time domain, the
UCI is multiplexed and transmitted on the PUSCH of the aperiodic
CSI. When the PUSCH of the semi-persistent CSI and the second PUSCH
group conflict with the PUCCH including the UCI in the time domain,
the UCI is multiplexed and transmitted on the PUSCH of the
semi-persistent CSI. The second PUSCH group may include at least a
part or all of one or more dynamically scheduled PUSCH and/or one
or more semi-statically scheduled PUSCH.
[0155] When the PUCCH including the UCI conflicts with the PUSCH of
the semi-permanent CSI and the PUSCH of the aperiodic CSI in the
time domain, the terminal device 1 multiplexes and transmit the UCI
on the PUSCH of the aperiodic CSI. When the PUCCH including the UCI
conflicts simultaneously with the PUSCH of the semi-persistent CSI
and the dynamically scheduled PUSCH in the time domain, the
terminal device 1 multiplexes the UCI on the dynamically scheduled
PUSCH and transmit the multiplexed UCI. When the PUCCH including
the UCI conflicts with the PUSCH of the semi-persistent CSI and the
semi-statically scheduled PUSCH in the time domain, the UCI is
multiplexed and transmitted on the PUSCH of the semi-persistent
CSI. When the PUSCH of the semi-persistent CSI and the third PUSCH
group conflict with the PUCCH including the UCI in the time domain,
the UCI is multiplexed and transmitted on one PUSCH selected from
the third PUSCH group. The third PUSCH group may include at least a
part or all of one or more PUSCH of the aperiodic CSI and/or one or
more dynamically scheduled PUSCH. For example, when the PUSCH of
the semi-permanent CSI and the PUSCH of the aperiodic CSI conflict
with the PUCCH including the UCI in the time domain, the UCI is
multiplexed and transmitted on the PUSCH of the aperiodic CSI.
Furthermore, when the PUSCH of the semi-persistent CSI and the
dynamically scheduled PUSCH conflicts with the PUCCH including the
UCI in the time domain, the UCI is multiplexed and transmitted on
the dynamically scheduled PUSCH. When the PUSCH of semi-persistent
CSI and the semi-statically scheduled PUSCH conflicts with the
PUCCH including UCI in the time domain, the UCI is multiplexed and
transmitted on the PUSCH of semi-persistent CSI.
[0156] When the PUCCH including the UCI conflicts with the PUSCH of
the semi-permanent CSI and the PUSCH of the aperiodic CSI in the
time domain, the terminal device 1 multiplexes and transmits the
UCI on the PUSCH of the aperiodic CSI. When the PUCCH including the
UCI conflicts with the PUSCH of the semi-persistent CSI and the
dynamically scheduled PUSCH in the time domain, the terminal device
1 multiplexes the UCI on the dynamically scheduled PUSCH and
transmits the multiplexed UCI. When the PUCCH including the UCI
conflicts simultaneously with the PUSCH of the semi-persistent CSI
and the semi-statically scheduled PUSCH in the time domain, the
terminal device 1 multiplexes and transmits the UCI on the
semi-statically scheduled PUSCH. When the PUSCH of the
semi-persistent CSI and the fourth PUSCH group conflicts with the
PUCCH including the UCI in the time domain, the UCI is multiplexed
and transmitted on one PUSCH selected from the fourth PUSCH group.
The fourth PUSCH group may include at least a part or all of one or
more PUSCH of the aperiodic CSI, one or more dynamically scheduled
PUSCH, and/or one or more semi-statically scheduled PUSCH.
[0157] When the PUCCH including the UCI conflicts with the fifth
PUSCH group in the time domain, the terminal device 1 multiplexes
the UCI on one PUSCH selected from the fifth PUSCH group and
transmit the multiplexed UCI. When the PUCCH including the UCI
conflicts with the fifth PUSCH group and the sixth PUSCH group in
the time domain, the terminal device 1 multiplexes and transmits
the UCI on one PUSCH selected from the fifth PUSCH group. The fifth
PUSCH group may include at least a part or all of one or more PUSCH
of the semi-persistent CSI and/or one or more PUSCH of the
aperiodic CSI. The sixth PUSCH group may include at least a part or
all of one or more dynamically scheduled PUSCH and/or one or more
semi-statically scheduled PUSCHs. The one PUSCH selected from the
fifth PUSCH group is obtained based on at least an index of a
serving cell to which each of the PUSCH included in the fifth PUSCH
is mapped, and/or the corresponding starting position of the PUSCH
included in the fifth PUSCH group.
[0158] When the PUCCH including the UCI conflicts with the PUSCH of
the aperiodic CSI and the seventh PUSCH group in the time domain,
the terminal device 1 multiplexes the UCI on the PUSCH of the
aperiodic CSI and transmits the multiplexed UCI. The seventh PUSCH
group may include at least a part or all of one or more PUSCH of
the semi-persistent CSI and/or one or more dynamically scheduled
PUSCH. When the PUCCH including the UCI conflicts with the PUSCH of
the aperiodic CSI and the semi-statically scheduled PUSCH in the
time domain, the terminal device 1 multiplexes and transmits the
UCI on the PUSCH of the aperiodic CSI. When the PUCCH including the
UCI conflicts with the seventh PUSCH group and the semi-statically
scheduled PUSCH in the time domain, the terminal device 1
multiplexes and transmits the UCI on the PUSCH selected from the
seventh PUSCH group. The PUSCH selected from the seventh PUSCH
group is obtained based on at least an index of a serving cell to
which each of the PUSCH included in the seventh PUSCH is mapped,
and/or the respective starting position of the PUSCH included in
the seventh PUSCH group.
[0159] When the PUCCH including the UCI conflicts with the PUSCH of
the aperiodic CSI and the dynamically scheduled PUSCH in the time
domain, the terminal device 1 multiplexes and transmits the UCI on
the PUSCH of the aperiodic CSI. When the PUCCH including the UCI
conflicts with the PUSCH of the aperiodic CSI and the eighth PUSCH
group in the time domain, the terminal device 1 multiplexes the UCI
on the PUSCH of the aperiodic CSI and transmits the multiplexed
UCI. The eighth PUSCH group may include at least a part or all of
one or more PUSCH of the semi-persistent CSI and/or one or more
semi-statically scheduled PUSCH. When the PUCCH including the UCI
conflicts with the dynamically scheduled PUSCH and the eighth PUSCH
group in the time domain, the terminal device 1 multiplexes and
transmits the UCI on the dynamically scheduled PUSCH. When the
PUCCH including the UCI conflicts with the eighth PUSCH group in
the time domain, the UCI is multiplexed and transmitted on the
PUSCH selected from the eighth PUSCH group.
[0160] When the PUCCH including the UCI conflicts with a plurality
of PUSCH of the aperiodic CSI in the time domain, and when the
plurality of PUSCH of the aperiodic CSI are used for the plurality
of serving cells, the terminal device 1 transmits the UCI related
to the PUCCH to the PUSCH of the aperiodic CSI to which the serving
cell has a low value of the serving cell identifier and transmits
the multiplexed UCI. When the plurality of PUSCH of the aperiodic
CSI are transmitted in the serving cell, the terminal device 1
multiplexes the UCI related to the PUCCH to the first PUSCH of the
aperiodic CSI in the time domain of the plurality of PUSCH of the
aperiodic CSI in the serving cell and transmits the multiplexed
UCI.
[0161] When the PUCCH including the UCI conflicts with a plurality
of PUSCH of the semi-persistent CSIs in the time domain, and when
the plurality of PUSCH of the semi-persistent CSIs are used for the
plurality of serving cells, the terminal device 1 multiplexes the
UCI related to the PUCCH to the PUSCH of the semi-persistent CSI to
which the serving cell has a low value of the serving cell
identifier and transmits the multiplexed UCI. When a plurality
PUSCH of the semi-persistent CSI are transmitted in the serving
cell, the terminal device 1 multiplexes the UCI related to the
PUCCH to the first PUSCH of the semi-persistent CSI in the time
domain of the plurality of PUSCH of the semi-persistent CSI in the
serving cell and transmits the multiplexed UCI.
[0162] When the PUCCH including the UCI conflicts with one or more
PUSCH of the aperiodic CSI and/or one or more PUSCH of the
semi-persistent CSI and/or one or more dynamically scheduled PUSCH
and/or one or more semi-statically scheduled PUSCH in the time
domain, a PUSCH for multiplexing and transmitting the UCI related
to the PUCCH may be determined based on at least y, c, and l in
Equation (1). For example, when the PUCCH including the UCI
conflicts with one or more PUSCH of the aperiodic CSI and/or one or
more PUSCH of the semi-persistent CSI and/or one or more
dynamically scheduled PUSCH and/or one or more semi-statically
scheduled PUSCH in the time domain, a PUSCH for multiplexing and
transmitting the UCI related to the PUCCH is determined with the
priority value P.sub.ri.sub.iUCI obtained based on Equation (1).
For example, the terminal device 1 multiplexes the UCI related to
the PUCCH on the PUSCH corresponded to the lowest P.sub.ri.sub.iUCI
and transmits the multiplexed UCI. That is, when the PUCCH
including the UCI conflicts with one or more PUSCH in the time
domain, the terminal device 1 multiplexes the UCI related to the
PUCCH to the PUSCH corresponding to the lowest P.sub.ri.sub.iUCI of
the one or more PUSCH and transmits the multiplexed UCI.
P.sub.ri.sub.iUCI(y, c, l)=N.sub.cellsN.sub.timey+N.sub.timec+l
[Equation 1]
[0163] N.sub.cells is the maximum number of serving cells.
N.sub.cells may be obtained with the higher layer parameter
maxNrofServingCells. N.sub.cells may also be a predetermined value
(for example, 16 or 32).
[0164] N.sub.time may be a value related to the number of time
domain resource allocation candidates of a PUSCH that can be
transmitted in one slot. For example, N.sub.time may be obtained
based on the higher layer parameters. For example, N.sub.time may
correspond to N.sup.slot.sub.symb. N.sup.slot.sub.symb is the
number of OFDM symbols included in one slot. In the carrier
aggregation in which the subcarrier spacing configuration .mu. is
configured for each of the plurality of carriers,
N.sup.slot.sub.symb may correspond to the carrier that is
configured with the largest subcarrier spacing configuration .mu..
In the carrier aggregation in which the subcarrier spacing
configuration .mu. is configured for each of the plurality of
carriers, N.sup.slot.sub.symb corresponds to the carrier that is
configured with the largest subcarrier spacing configuration .mu.
among the one or a plurality of carriers of PUSCH, which conflict
with the PUCCH including the UCI transmitted (allocated) in the
time domain. When the largest subcarrier spacing configuration .mu.
is 2 and the CP configuration is an extended CP (extended cyclic
prefix), N.sup.slot.sub.symb is obtained with the
N.sup.slot.sub.symb for the carrier when the subcarrier spacing
configuration .mu. is 2 and the CP configuration is a normal CP
(normal cyclic prefix). For example, N.sub.time may correspond to
ceiling (KN.sup.slot.sub.symb). The value of K may be obtained
based at least on .mu.. The value of K may be obtained by
2.sup.(.mu.-.mu.PUCCH). .mu.PUCCH is the subcarrier spacing
configuration of a carrier in which PUCCH is used. ceiling
indicates a ceiling function. The ceiling function outputs the
smallest integer that is greater than an input value.
[0165] For example, when .mu.=3 and .mu.PUCCH=1 are configured,
K=4, N.sup.slot.sub.symb=14, and N.sub.time=56.
[0166] When .mu.=0 and .mu.PUCCH=2 are configured and the CP
configuration of the carrier using the PUCCH is an extended CP,
K=0.25 and N.sup.slot.sub.symb=14, and N.sub.time=4.
[0167] When .mu.=2 and .mu.PUCCH=4 are configured and the CP
configuration of the carrier using the PUSCH for .mu.=2 is an
extended CP, K=0.25 and N.sup.slot.sub.symb=14, and
N.sub.time=4
[0168] c is the index of the serving cell (c=0, 1, . . . ,
N.sub.cells-1).
[0169] In the fourth example in FIG. 6, c=1 may be configured for
PUSCH 632 and PUSCH 633, and c=0 may be configured for PUSCH 630
and PUSCH 631.
[0170] l may be indexed in the order from the earliest starting
position of PUSCH transmission in each of the serving cells. l may
correspond to the index of the first OFDM symbol of the PUSCH.
[0171] In the third example in FIG. 6, l=0 may be configured for
PUSCH 622, l=1 may be configured for PUSCH 623, l=2 may be
configured for PUSCH 624, l=3 may be configured for PUSCH 620, and
l=4 may be configured for PUSCH 621.
[0172] In the fourth example in FIG. 6, l=0 may be configured for
the PUSCH 632, l=1 may be configured for the PUSCH 633, l=0 may be
configured for the PUSCH 630, and l=1 may be configured for the
PUSCH 631.
[0173] y is a weighting coefficient used for determining a priority
of types of PUSCH that include at least a PUSCH of the aperiodic
CSI, a PUSCH of the semi-persistent CSI, a dynamically scheduled
PUSCH, and a semi-statically scheduled PUSCH. The value of y may be
configured for each PUSCH type.
[0174] For example, y=0 may be configured for a PUSCH of the
semi-persistent CSI, y=1 may be configured for a PUSCH of the
aperiodic CSI, y=2 may be configured for a dynamically scheduled
PUSCH, y=3 may be configured for a semi-statically scheduled
PUSCH.
[0175] In another example, y=1 may be configured for a PUSCH of the
semi-permanent CSI, y=0 may be configured for a PUSCH of the
aperiodic CSI, y=2 may be configured for a dynamically scheduled
PUSCH, and y=3 may be configured for a semi-statically scheduled
PUSCH.
[0176] In one example, y=2 may be configured for PUSCH of the
semi-permanent CSI, y=0 may be configured for PUSCH of the
aperiodic CSI, y=1 may be configured for a dynamically scheduled
PUSCH, and y=3 may be configured for a semi-statically scheduled
PUSCH.
[0177] In one example, y=3 may be configured for PUSCH of the
semi-permanent CSI, y=0 may be configured for PUSCH of the
aperiodic CSI, y=1 may be configured for a dynamically scheduled
PUSCH, and y=2 may be configured for a semi-statically scheduled
PUSCH.
[0178] A first aspect of the present disclosure is a terminal
device, comprising: a receiving unit that receives a PDCCH and
receives a PDSCH scheduled based on at least the PDCCH, wherein
when the PUCCH conflicts with one or more PUSCH in a time domain,

whether each of the one or more PUSCH is a PUSCH of semi-persistent
CSI, and a UCI corresponded to the PDSCH is transmitted on the
